.To aZZ whom, it may concern .wire rods can be produced by rolling operation of much smaller gage or diameter than it has heretofore been practical to make by the ordinary processes of production also, to afford a process whereby several wire rods maybe simultaneously produced or rolled from a single billet or bar otlmetal and ata single heat.

The nature of my improved process of forming wire rods of small size consists in reducing the bar by continuous rolling until t-hescctional area of the partially-rcduced rod is nearly the same or but slightly greater than the required sectional area of the finished product, then molding the rod by the following pair or pairs of rolls into a form or shape composed of a seriesof two or more ribs counectedto each other by a thin web, then dividing the rod along the thin webs and directing the separate strands or rib p ortions-through separate grooves ordiesthat round or form each strand into a separate finished wire rod of the dimension required.

In carrying out my process the best plan now known to me is to employ a continuous rolling-mill fitted near the latter end with means for forming and separating the. ribbed rod, and with duplicate guides and dies following for receiving and working the several strands, so that the reduction, separation, and

finishing can be accomplished direct from the bar and at a single heat.

For sev ering the rodinto separate strands, any suitable mechanism may be employed. One device which may be employed for the purposeis a pair of stationary shear-blades or sharp jaws, against the interangle of which the invention is to al red is forced or drawn by the action of the working-rolls. These shear blades or jaws may .be adjust-able, so as to be set closer or more open to change the contact-point as any portion of their edges becomes rounded or dulled. The rolls for reducing and finishing the rods may be of the ordinary kind, with dies or grooves of the required size and shape, the guides being constructed in a manner to meet the requirements of the separate rod.

As my improvements in mechanism for work ing this process form the subjectmatter of separate Letters Patent, it will not be necessary to herein describe the devices more fully in detail.

In the drawings I have illustrated the manner of passing the rod through the rolling-mill and the shapes at some of the principal stages of my improved process.

Figure 1 is an outline sketch, indicating the course of the rod through a continuous mill.

Fig. 2 is a similar diagram, showingthe adaptation in mills of the class known as the Belgian niilh Fig. 3 shows my improved shear for separating the rod into independent strands. Figs. 4, 5, 6, 7, and 8 show sections of the rod at difierentstagcs of reducti onviz.. as partially reduced, as in ribbed conditionizs divided into separate strands, and as finished.

. These sections are drawn to a scale twice the actual size. The form or outline of these shapes or sections can be modified as required to make a round, flat, square, hexagonal, oval, or'other shaped wire.

In reference to the drawings, a denotes the reducing-rolls; b, the wire rod; a, the roll for ribbing the rod, 0, the shears or dividing device; J, the finishing-rolls; e, reels on which the finished rods are coiled.

By my process herein described the wire rod remains at a size sufficient to retain a good forging-heat to near the final action, and it is then quickly reduced to several small-sized rodsbefore it has time to become cold and hard. Thus it is practical to produce wire rods several sizes smaller by my process than can be done by the ordinary process of rollin My process is adapted for making wire for barbed fencing, telegraph-lines, and similar purposes direct from the rods withoutthe need of drawing the wire after it is rolled, thus making a great saving in the expense of production, while for fine-drawn wire the rods thus produced are superior, as they require a less number of drawings than a larger rod to reduce them to any given size, and the wire made therefrom is less brittle than corresponding sizes which have passed a greater number of drawings. The process could be worked by reducing the rod to the ribbed condition at one rolling, and then reheating it before it is subjected to the dividing and finishing operations. This method, while it is included within the scope of my invention, does not at present seem to me to be so advantageous and desirable as to complete'the entire operation at av single heat and by continuous action.

Vhat I claim as of my invention, and de sire to secure by Letters Patent, is

l. The improvement in the art of making wire, which consists in reducing abillct orbar l into a rod, composed of a series of ribs con= nectedby thin web, and subsequently dividing the same along the web and forming an independent wire rod of each rib portion.

2. The improved process of forming wire rods by continuous rolling, which consists in reducing the billet or bar, then converting it by rolling into a series of incipient wire rods connected by longitudinal webs, dividing the bar along said webs to form separate rods, and finally rounding up or imparting the finished form to said rods separately, as independent wire rods of small size, as hereinbcfore set forth.
